Single SLM-based binocular holographic near-eye display and CGH generation method for the same

A near-eye display method comprising:

• emitting, by a light source, light;
• modulating, by a modulator, emitted light and reconstructing a hologram including a first hologram image and a second hologram image;
• splitting, by a splitter, the reconstructed hologram, and distributing the hologram to a plurality of paths;
• focusing, by a first eyepiece lens, only the first hologram image of the split hologram on a first eyeball of a user;
• and
• focusing, by a second eyepiece lens, only the second hologram image of the split hologram on a second eyeball of the user,
• wherein the first hologram image is formed on a zone that is out of an imaging zone formed by a focal distance of the second eyepiece lens as a virtual image, and
• wherein the second hologram image is formed on a zone that is out of an imaging zone formed by a focal distance of the first eyepiece lens as a virtual image.

A near-eye display comprising:

• a light source configured to emit light to a modulator;
• a modulator configured to reconstruct a hologram in which a first hologram image and a second hologram image are represented with different depths;
• a splitter configured to split the hologram reconstructed in the modulator and to distribute the hologram to a plurality of paths;
• a first eyepiece lens configured to focus only the first hologram image of the split hologram on a first eyeball of a user;
• and
• a second eyepiece lens configured to focus only the second hologram image of the split hologram on a second eyeball of the user,
• wherein the first hologram image is formed on a zone that is out of an imaging zone formed by a focal distance of the second eyepiece lens as a virtual image, and
• wherein the second hologram image is formed on a zone that is out of an imaging zone formed by a focal distance of the first eyepiece lens as a virtual image.
